LEONARD S. BALUTA, OF BERWIOK, PENNSYLVANIA.

REEL.

' 7 Application filed July 19,

To all whom it may concern:

Be it known that I, LEONARD S. BALUTA, a citizen of the United States,residing at Berwick, in the county of Columbia and State ofPennsylvania, have invented certain new and useful Improvements inReels, of which the following is a specification.

This invention relates to motion picture film reels and attachmentstherefor, and is an improvement of my Letters Patent #1,232,753 issuedto me July 10, 1917, and on of the prime objects of the presentinvention is to provide an improved reel embodying a novel type of huband flanges, whereby the film can be readily and quickly irrespective ofthe posi- Another pri e object of the invention is to provide an provedmeans of forming the hub for recei ing and holding the flexible elementcarry'i g the film clasp whereby the same will be against displacementand eliminate the necessity of providing any extraneous means forattaching the flexible element to the hub.

A further prime object of the invention is to provide a reel includingside flanges having relatively large symmetrically arranged openingsstamped therein for permitting the easy insertion of the operators handin the reel, and to lighten the weight of the reel to permit the easyhandling and shipping thereof, and a novel hub structure formed from apair of sections, which can be struck with a single stamping operationfrom the portions of the metal struck from the flanges to form theopenings therein.

A further object of the invention is to pro vide a novel two part reelhub having means formed thereon for spacing the parts or sec. tions toform a pair of diametrically opposed key ways, the meeting faces of thesections having struck out tongues for engaging the flexible clampcarrying element to hold the same in position, the sections also havingopenings for receiving the tongues so as to prevent the slipping of theflexible element from off of the tongues.

A further object of the invention is to provide an improved means forforming the hub sections so as to permit the film clasp to lie flushwith the periphery thereof, and thus eliminate all projecting portionson the hub which would tend to bulge the various convolutions of thefilm. I

A further object of the invention is to ifectively held in position v1920. Serial No. 397,294.

i provide an improved means for attaching the film to the reel, whichmeans permits the use of a relatively short flexible element carryingthe spring clasp which eliminates the necessity of coiling the flexibleelement around the hub a number of times.

A still further object of the invention is to provide an improved movingpicture film reel of the above character, which is durable and eflicientin use, one that is simple and easy to manufacture, and one which can beplaced upon the market at a reasonable cost.

With these and other objects in View, the invention consists in thenovel construction, arrangement and formation of parts as will behereinafter more specifically described, claimed and illustrated in theaccompanying drawing, forming a part of this specification, in whichdrawings:

Figure l is a side elevation of the improved reel.

Figure 2 is a diametric section through the same showing the methodpursued in attaching the film end to the film clamp car ried by theflexible element.

Figure 3 is an enlarged vertical section through the reel and hubillustrating the means for attaching'the flexible element carrying thefilm clamp to the hub.

Figure 4 is a simllar view of the flexible element and film coiledaround the hub and illustrating the position'of the film receiving claspwhen the same is in operative position. .t

Figure 5 is an enlarged sectional view through the improved clasp usedinconnection withthe reel.

Figure 6 is an enlarged transverse sectional view through the clasp.

Referring to the drawings in detail, wherein similar referencecharacters designate corresponding parts throughout the several views,the letter A generally indicates the improved reel, which includes theside flanges B and the hub C, and D designates the attaching means forthe film E.

The reel flanges B are of disc like configuration and are preferably;formed of sheet metal and are provided on opposite sides of the axialcenter thereof with diametrically opposed relatively large openings 10.The

openings 10 are of substantially rectangular to permit the easy handlinthereof. The metal taken ings 10 is utilized to form the hub C w ichwill be hereinafter more fully described. It thus can be seen that allof the metal is utilized thereby eliminating all waste of material. Theside flanges B are otherwise formed similar to the usual flanges of amotion picture reel.

The hub C of the reel A is preferably formed of two companion sections11 and 12 which as stated, are formed from the metal taken from theopenings 10. This metal is stamped to provide a body portion 13 andarcuately curved flanges 14. The terminals of the flanges 14 are bentinwardly toward each other as at 15. This provides a space 16intermediate the flanges the purpose of which will be hereinafter morefully described. The body portions 13 of the hub? sections 11 and-12 areadapted to be posi-f tioned in arallel relation to each other and areprovided with pairs of struck in tits 1'? which space the body portions13 soas to provide diametrically opposed keyways 18 on the oppositesides of the semi-cylindrical barrels 19 which provides the 0 ening forreceiving the supporting shaft Fnqt shown). The opposite ends of thebody portions 13 are provided with outwardly extending lugs 20 which areadapted to fit in T-shaped openings 21 formed in the side flanges B atthe axial center thereof. If so desired these lugs may be upset, so asto hold the hub sections and guide flanges in correct relation. However,the arcuate flanges 14 are also provided with outwardly extendingbendable tongues 22 which are inserted through openings 23 formed in theside flanges. After the tongues 22 have been inserted in the openings 23the same are bent over as clearly shown in Figures 1 and 2 of thedrawings.

The hub sections 11 and 12 are adapted to 1 receive between the bodyportions 13 thereof the flexible strip or tape 25 which 'formsa portionof the film holding member D which will be hereinafter more fullydescribed. To hold the inner end of the flexible tape or strip-25between the body portion 13 of the hub sections 11 and 12, the hubsections are provided with struck out right angularly extending pointedpenetrating tongues 26 which are adapted to extend through the flexibletape or strip 25. The body portion 13 of the hub section which is notprovided with the struck out prongs is provided with openings 27, whichare adapted to receive the tongues so as to prevent displacement of theflexible strip or tape therefrom.

The film. holding device D is similar to the device shown in my priorpatent with the exception that the flexible tape 25 is formed shorter sothat the ing the same around the hub a number of and shipping om the 0en-.

necessity of coilthe film clasp 29 is drawn through one of the openings10 with the inner end of the film E as clearly shown in Figure 2 of thedrawings. -This permits the convenient at- Q taching of the inner end ofthe film to the clasp. The clasp is also of novel construction and asshown is of S-shaped configuration and includes the body portion 30 andthe folded spring tongues 31 and 32. The spring tongues 31 and 32 engagethe opposite faces of the body plate 30 and are formed by bending theopposite. end of the plate=back upon itself. The free terminals of thespring tongues 31 and 32 are bent outwardly. as'at 33 and provided witha plurality of equi-distantly spaced prongs 34 which are adaptedtoengage in the usual openings formed in the side of the film. The

prongs 34 formed one of the gripping mem-- bers for the film. The bodyportion 30 of the clasp is provided with a longitudinally extending slot35 and each of the spring tongues 31 and 32 are provided with struck inlongitudinally extending ears 36 which are adapted to lie within theslot. ne of the longitudinal erlges'of the. body plate 30 is providedwith a pair of outwardly extending prongs 36' which-form the secondmeans for engagingthe film to prevent the displacement thereof. Theseprongs 36' are also adapted to engage in the film open ing. The opposite'edge of the body plate 30 isprovided with an extension 37 which isprovided with an opening 38 and this slot is adapted to receive thefolded end *39 of the flexible strip or ribbon 25. The folded end of theflexible strip or ribbon is sewed or otherwise. secured together. theend of the film in position on the clasp. one end of the same is slidbetween one of In placing the flexible wings or tongues 31 and 32 andand thus form a third means for preventing the disengagement of the filmend from "the clamp. The clasp 29 is formed alike on opposite sides andthus the same is reversible and permits the film to be wound in eitherdirection upon the hub. The space 16 between the wings 15 is adapted tore ceive the clasp 29 so that the same can lie flush with the peripheryof the hub. This is an important feature, as all protruding parts on thehub are eliminated and the film is permitted to be evenly wound on thehub without any bulges therein.

The film reel is adapted to be placed upon the market with the filmattaching member D secured thereto and it can be seen that theconvenient means of attaching the film end thereto will readily appealto moving picture machine operators as considerable time and labor willbe saved in attaching the film thereto. The cheapness of construction ofthe reel will also appeal to a manufacturer as the same can be placedupon the market at a slight cost and still leave a good margin ofprofit.
